2 g of a gas initially at 4.00 atm is compressed from 8.00 l to 2.00 l at constant temperature. what is the resulting pressure in atm of the gas?

Based on the periodic table above, which of the following elements is a metal?

On my bike, i was able to travel 40 miles in one hour. from this information, we can determine the bike's a. speed. b. velocity. c. acceleration. d. direction.

Types of problems are generated by resource extraction and usage?

9. An 800 kg police boat slows down uniformly from 50 km/h [E] to 20 km/h (E) as it enters a harbour. If the boat slows down over a 30 m distance, what is the force of friction on the boat? (Hint: You will need to convert the velocities into m/s.)

When cars are equipped with flexible bumpers, they will bounce off each other during low-speed collisions, thus causing less damage. In one such accident, a 1850 car traveling to the right at 1.40 collides with a 1350 car going to the left at 1.10.

8. A gas is contained in a horizontal piston-cylinder apparatus at a pressure of 350 kPa and a volume of 0.02 m3. Determine the work done by the piston on the gas if the cylinder volume is increased to 0.15 m3 through heating.

A 75.0 kg person stands on a scale in an elevator. (a) What does the scale read (in N and in kg) when the elevator is at rest?

The hinge at A and cable BDC support beam ABC. Cable BDC passes over the pulley D that is pinned to the ceiling. (Assume that the + x-axis is to the right and the + y-axis is up along the page.
